DISINFECTIN G APPARATUS.

Application filed December 4, 1925.

This invention relates to disinfecting apparatus and has for its primary object the provision of simple means whereby the seat of a water-closet will be automatically sprayed when it is raised so that it will be kept in a sanitary condition and the communication of disease will be avoided. The invention seeks to provide an apparatus which may be readily applied to any standard toilet and so arranged that when the seat is, swung upwardly a spray of disinfectant will be delivered upon the surface of the seatso that all disease germs. will be destroyed. The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features being particularly pointed out in the appended claims.

In the accompanying d awings.

0 Figure 1 is an elevation of a portion of a toilet bowl having my disinfecting spray apparatus applied thereto.

Figure 2 is a plan view of the apparatus removed from the seat.

Figure 3 is an enlarged section on. the line 33 of Figure 2. s

Figure l is an enlarged the line a eof Figure 1. I v

Figure 5 is an enlarged detail section on 0 the line 5-5 of Figure 2.

Figured is a detail elevation.

Referring now to the drawings moreparticularly, the reference numeral 1 indicates a portion of a. toilet bowl of any approved 5 type and illustrated as having a rear flange or lip 2 upon which. the seat- 3 is mounted by brackets at formed with bolts. 5 adapted to extendthrough said flange and be clamped theretoby nuts 6 in an obvious manner.

detail section on The seat is carried by seat arms 7 which are,

of general angular formation and are bolted or otherwise secured to the under side of the seat at the back edge thereof and have ranches 8 which are extended rearwardly i beyond the brackets 4 and are pivotally mounted thereon, as indicated at 9. Disposed at their front ends between the top surface of the flange or lip 2 and the shoulders 10 of the brackets 4, are the front ends of supporting plates or arms 11 which extenddownwardl y and rearwardly in rear of the bowl and have their lower rear. portions formed into shallow concave plates 12 which are adapted topartially encircle and to supi port cylinders 13; As shown. clearly in Figures 1 and 3, the supporting arms 11 are Serial No. 73,239.

bolts 5, as clearly shown in Figure 3, being clamped against the under side of the lip or flange 2 by the nuts 6. The cylinders 13 are held rigidly upon the plates 12 by clamping bands 16 which are engaged around the cylinders and have their ends secured by bolts QS GITQCl through mating lugs 17 in an obvious manner. The bands may conveniently be formed integral with the respective edge portions of the plates 12 so that they will be iirmly united with the plates and may be easily engaged around and secured to the cylinders. Upon referring to Figure 2, it will be noted that a plate 12 and a corre sponding cylinder 13 is provided in alinement with each of the seat-carrying brackets 7 and 8 and each of said arms 8 is connected by a link 18 with the upper forward end ofa piston rod 19 extending through the upper head of the cylinder and connected, within the cylinder, to a piston 20. An expansion spring 21- is arranged within each cylinder between the piston and the upper head 22 of the cylinder, as shown. clearly in Figure 3, so that when the seat 3 is not in use, the expansion of the springs will automatically raise the seat and operate the pistons to cause the seat to be sprayed. The heads 22 and 23 of the cylinders may be of any convenient or preferred form and are substantially circular cap threaded onto the respective ends of the cylinders in? an obvious manner. The supporting plate 12 may be provided with inwardly projecting spurs arranged to bear upon the upper heac so as to prevent the same becoming loose under the action of the piston and thereby decreasing the eiiiciency ofthe device. The piston rod does not lit tightly within the upper head so that the opening. in the head will provide suliicient vent to prevent. air being trappedwithin the cylinder in quantities sufiicient to prevent the piston moving through afull stroke. VVhenthe seat 3 is lowered for use, the corresponding swinging movement of the brackets and arms 8 will i the lower head 23 of each cylincer, a nipple 27 in its outer end i=6 havi g: an inlet port l nor-1c with an e 1 no port 28 at its r end. tl e bore of l the nipple being of a r diameter than said ports and a ball valve 30 which may play \v upon reference to Figure stroke ot the piston.v th, ball will lwn away from the inlet port 2? so that air may then How through the nipple g der, escaping from the nipple through the lateral ports 31 adjacent the inner end thereof. Upon the force stroke of the piston, the valve will be driven to seat again t he port 2? and thereby cut oil the tlow of air through said port so that as the compression stroke continues, the air will be driven out through the discharge tubes under considerable pressure.

The cisc iar e tubes 25 lead from the respcctive cylinders to a spray nozzle 32 which may be of any convenient or approved detail construction. and is mounted upon ti top of a spray chamber 83 which is secured upon the lip or flange 2 or the bowl at the center or" the same. The outlet nipple 3-1- of the spray nozzle directed upwardly at the :ropcr angle to deliver a spray upon the seat as the same assumes or closely approaches the position shown in Figure 1. The spray chamber 33 may be mounted upon the bowl in any preferred manner and I have shown it seated upon a plate 35 between flanges 3t) and held against movement by plates or irackets 37 secured upon t said plate be- 118 tween the flanges 36 and bearing against the opposite sides oi the spray chamber. The plate which provides the support for the spray chamber, is extended between the backets l1 and has its extremities rest upon and secured to said brackets, the sale extremities being formed with downturned flanges 38 at their rear edges bearing closely against the intermediate portions of the said brackets 11 whereby the plate will be firmly supported. It will also be noted, upon reference to Figure 2, that the plate is provided with slots 39 disposed transversely of the supporting brackets so that the securing bolts 40 may be accommodated notwithstanding variations in the distance between the brackets l, due to ditl'erent forms or proportions in the toilet bowl. In order. al o, to accommodate the device to bowls of different widths, the outer ends of the supp rting plates 12 are connected by a brace ll consisting of flat straps 42 having their irner ends or rlapped, as shown in Figure 2. anc provided with longitudinal slots l l through which a securing bolt ll is passed.

" 1e spray chamber 33 is intended to hold ply of disinfectant convenient to the axle 32, which has a nipple l5 c3;- downwardly through the top of the hamber so as to be in'imersed in th;

sprav liquid within the chamber. ll hen the p35 1 v i ll and escape through the nipple ill over the seat 3 in the form ot a very line. Inu t. 'l h:-

chamber 33 is in direct commnuication. through a pipe 410 with a supply reservoir 4-", which may be mounted in any convenient nanner and will preferably be supported nnediately adjacent one end of the flush nk 4:8. The pipe l6 leads from the bottom i the reservoir or supply tank 4-? into the 3. ray chamber through the side ol the (JU- sizine. and is connected with the chamber a coupling head ell) in which the end of the pipe is threaded so as to alinc axially with a port in the said coupling head. The coupling pr jects into the chamber 3 as shown clearly in Figur 5, and has a bore 51 accommodating a ball valve vhich is adapted to seat over an outlet port 53 in the inner end of the coupling. Fulcrumed u mu the coupling above the outlet port an angle lever 5st, to the upper arm of which is :-ecured a float 55, the depending arm ol lever being connected by a pin and slot connection, indicated at 56, with the stem 53? ot the valve which stem extends through the port Obviously, as the level of the li uid chemical in the chamber 3 t'alls through use of the chemical, the tioat 553 will descend and rock the lever Bl about its fulcrum so that the valve will be unsealed and an additional supply oi the chemical may flow from the tank 1? into the cham i-cr All the level oi the lltillltl rise the tloat will. of course, he returned to its normal position and eventually the ball will be seated so as to cut oli turther flow of the liquid. This arrangement maintains a substantially constant level of the liquid in the chamber 33 and thereby prevents overflow hrough the spray nozzle and the outlet nipple of the latter. notwithstanding that the reservoir may be placed at a considerable elevation. The reservoir may also be of substantially greater capacity than the chamber and may he refilled without requiring access to the said chamber.

A lid is shown in the drawings carried by arms 61 which are pivoted upon the bolts 9 and pads or cushions 62 are provided to receive possible impact of the seat arms and thereby avoid cracking of the flange 2. I also provide latches 63 which are pivoted upon the plank and are adapted to be engaged around the seat arm 7, as shown in paratus is of such form and so arranged that it may be disposed below the flush tank and at the rear of the bowl, as clearly shown, so that it will be out of the way and will not be apt to be damaged by chance blows. The

construction of the several parts is very simple so that the apparatus is not apt to get out of order and repairs will seldom be needed. 7
